Question

If a, b c are in AP then, write the value of c-b in terms of a and b​

Answer 1

Answer:

b-a

Step-by-step explanation:

by definition of AP

there is a common difference in terms of AP

so b-a=c-b

Answer 2

Let, a=a, b=a+d, c=a+2d

therefore, c-b=a+2d-(a+d)

= d

hence, c-b=d=b-a

∴c-b, in terms of a and b is b-a
